I loved staying at KoKo's apartment in Ari! It was very clean and had all the necessities for a long stay. The location is very convenient, near Ari BTS and with many food options available. The condo is very clean and modern - I especially enjoyed using the pool, skygarden and co-working space. The gym is very small, but it does the job if you get creative with your workout.
KoKo is an amazing host and very prompt and friendly with his communication. He was very understanding when I had to leave a night earlier due to a family matter and my friend could stay in the Airbnb instead.
The only thing I would point out is that the apartment is located on the ground floor and cleaning staff frequently passes the windows to hang up towels next to the bedroom window, so you have to keep the blinds down to have privacy. This is one of the reasons I didn't spend so much time working in the apartment because there wasn't any natural light coming in and it was pretty dark. Next time I would prefer an apartment that is located higher up, but this is just a small thing and didn't make my stay any less enjoyable.
